Garbage in, garbage out - it's an axiom that applies to many aspects of enterprise development, but none more so than building reliable and robust Web applications and integration projects with XML. Since its inception, XML has been seen as the cure-all for every problem related to Web application development. However, poorly written XML can either slow down an integration project, or worse, cause the integration project to collapse. It's important to understand some of the inefficiencies of XML, as well as how you can "clean up" and prevent the use of poorly written XML in development projects. After all, system performance is only as good as the data received and the instructions given. If errors are contained in the XML, it is more likely than not that the system will crash. One of the main benefits of XML is that it provides mechanisms for verifying document val... (more)

Strategies for Securing Java Code

Java security is an overwhelming issue. For a truly secure application, you need to prevent hackers from entering the system, and you need to ensure that code safeguards security if a hacker does break in. Moreover, there is no room for error. If you anticipate and prevent hundreds of security vulnerabilities but overlook just one, a hacker can still wreak havoc on your system. This article introduces some fundamental strategies for writing Java code that remains secure if a hacker manages to enter the system. Essentially, writing secure code requires a shift in thinking.

It's Time to Prevent Poorly-Written XML

Since its inception XML has at times been seen as the cure-all for every problem related to Web applications and integration projects. However, poorly written XML can either slow down an integration project, or worse, cause the integration project to collapse. When developing integration systems such as Web services or any other business-to-business function, developers may encounter the following problems when writing XML: Non-verifiable code - XML is supposed to be easily validated by use of Document Type Definitions (DTDs) or schemas. Frequently however, DTDs and schemas may... (more)

SOA Best Practices - Four Steps to Securing Your Web Services

Dr Adam Kolowa (pictured), Founder & CEO of Parasoft and panelist at SYS-CON Events'  "SOA Web Services Power Panel" at SOA Web Services Edge Conference & Expo - June 5-6, 2006 - in New York City, writes: Security has the inherent nature of spanning many different layers of a Web Services system. Web Services vulnerabilities can be present in the operating system, the network, the database, the Web server, the application server, the XML parser, the Web Services implementation stack, the application code, the XML firewall, the Web Service monitoring or management appliance, or just...
